# KDAH vs Watch ECG Pro

The clearest difference is in-app purchases: KDAH at none against Watch ECG Pro's 3. KDAH also leads on ads (none vs shown) and review sentiment (58% vs 25%). Watch ECG Pro's advantage is ratings volume (64 vs 4). On price, rating, update cadence and device support there is nothing between them.

Both are free to download. Watch ECG Pro sells 3 in-app purchases, starting at $6.99 per 7 days. KDAH asks for nothing beyond the download.

Watch ECG Pro holds the better App Store score, 4.4 against 4.3. That said, the two scores are not equally well evidenced: Watch ECG Pro has 64 ratings behind it against 4, so its average is the more settled of the two. Written reviews complicate that: 58% of KDAH's written reviews are positive against 25% of Watch ECG Pro's, so the app with the better star average is not the one people write more warmly about.

KDAH ships an update monthly, Watch ECG Pro every 2 months. The most recent releases landed on November 1, 2026 and November 3, 2026 respectively.
